Description

The present invention relates firstly to a device for delivering objects stored online.

It also relates to an installation capable of implementing the device according to the invention.

The delivery device presented here comprises means for guiding the stored objects, an object stop placed at the head of the line in order to retain it and means for ejecting said object out of the stop when the delivery of the object is controlled.

The installation according to the invention incorporates one or more delivery devices within one or more pieces of furniture.

Stock management is a growing problem in the field of the sale of pharmaceutical or parapharmaceutical products.

What's more, the pharmacist or the salesperson wastes a lot of time research of the product requested by the customer when this time could be devoted practical or medical advice.

In addition, conventional methods of drug storage, in particular by different drawers, can be bulky and not very practices for identifying different types and brands of drugs.

Different drug distribution and storage devices have been proposed.

In this area, we particularly know the document EP-A-0.515.350 which has an ejection device for an accumulation device used to receive and deliver objects one by one, in particular for a device accumulation of an order preparation facility for shipping.

The accumulation device is such that the objects are applied according to a prestressed against an outlet end in the accumulation device.

The ejection device according to this document comprises an abutment shoulder to allow the object closest to the exit end to be supported.

In addition, a lifting piston is arranged in front of the abutment shoulder. and is movable perpendicular to the delivery direction between a position located essentially in the plane of the support surface of the objects to be delivered and a position corresponding to the upper edge of the abutment shoulder.

This technique is based on a box ejection system which uses a lifting piston moving perpendicular to the delivery direction.

This piston is actuated by a pressurized fluid which is, in practice, air compressed.

Such a device has the disadvantage of being mechanically difficult to implement. work since it is based on a pneumatic system requiring resources relatively heavy such as an air compressor and complex circuits for convey air.

Furthermore, such a design has a low modularity at the level storage spaces.

The present invention overcomes the drawbacks of the devices currently known and proposes in particular to lighten the structure of the installations of delivery of objects such as drugs.

To do this, the invention has the advantage of making it possible to dispense with the use of a pressurized fluid and to implement actuations supplied with low power electrical energy.

What is more, the invention aims to make more flexible the use of devices for delivering objects, in particular by allowing better modularity of the installations.

To do this, it uses technical connection features which avoid heavy, complex, costly and poorly suited to modularity.

This is how the user of the piece of furniture or an installation can himself proceed to a new configuration of this piece of furniture.

Another advantage of the invention is to allow control of the delivery of the stored objects via a data bus corresponding to the bus electric power supply.

The invention also makes the installation more reliable by minimizing the necessary connection operations and using resources actuation with an uncomplicated design.

Other objects and advantages will become apparent from the following description which is however only given for information.

Figures 5a, 5b, 5c and 5d show the lower part of a slide during different stages of operation of the delivery device.

Figure 6 is a side view of a slide showing an example of realization of the operated electrical contacts.

Figure 7 is a general view of a particular mode of implementation of an installation according to the invention and particularly of its control means.

Figures 8 and 9 illustrate a variant of the invention with regard to the operation of the delivery device.

Referring to Figures 1 and 2, we see that an installation according to the invention comprises one or more pieces of furniture like that marked 1 in these figures.

Such a piece of furniture commonly comprises a frame structure and a internal volume within which are integrated devices for delivering objects 2, 24 stored online.

As shown, the delivery devices can be stacked or juxtaposed in order to fill the entire interior volume of the cabinet 1.

Preferably, the objects stored on a line are substantially same nature.

In the case of application to the dispensing of drugs, this will be a line of same drugs.

To support the objects 2, 24, guide means are present.

It is, in the case of the figures, a substantially elongated member having a sliding surface 8 capable of coming into contact with the lower part of the objects 2, 24.

In the particular mode illustrated in the figures, these guide means are constituted by a slide 3 which can be seen to be oriented in the direction of the line of objects 2, 24.

Figure 3 shows a general view of such a slide 3 while Figure 4 illustrates the presence of a sliding surface 8 for the stored objects 2, 24.

In the example of the figures, the sliding surface 8 of the slide 3 is inclined with respect to the horizontal so that the object 2 at the head of the line is partly bottom of the sliding surface 8.

In this way, under the effect of weight, the stored objects have a tendency natural to move towards the lower part of the slide 3 which constitutes the area where the delivery takes place.

Of course, other means could have been used to achieve this. orientation towards the delivery area and in particular push systems by the intermediary of springs could be implemented.

In a particular embodiment, a slide 3 serves both to maintain and guide objects on a line but also guide a second line objects placed side by side with the first.

In this sense, a second sliding zone 8 may appear such that shown in figure 4.

The delivery device according to the invention also comprises a stop 9 of the object placed at the head of the line.

Figure 4 perfectly shows an embodiment of such a stop in the form of a flange protruding at the bottom of the sliding surface 8.

The stop 9 intercepts the sliding surface 8 in order to retain the object 2.

The device presented here also includes means for ejecting the object. 2 out of stop 9.

The ejection means make it possible to deliver the object 2 from its contact with the stop 9.

In a particular embodiment, the stop 9 and the ejection means consist of a single retractable part.

When the part is raised, it constitutes a stop for object 2.

When this part is removed or retracted, it frees delivery by object drag 2.

According to another embodiment, as it appears in the different figures and in particular in FIGS. 5a, 5b, 5c and 5d, the ejection means comprise a lifting means 10 able to raise the front part of the object 2.

For the proper understanding of this description, and for the rest of this is understood by the area before or part before the part of an object or element component of the device placed substantially on the side of the delivery zone of the object.

Conversely, by back we mean the part of the objects where the elements components of the device placed substantially towards the rear of the cabinet 1.

The lifting means 10 has the function of slightly raising the front part of object 2 so that it exceeds the height of the stop 9.

To do this, the lifting means 10 can be constituted by a wing wheel 11, these wings being able to be applied under the box 2 in order to exert an effort of thrust on it.

It should be noted that, advantageously, the wings 11 also serve to transmitting a rotational movement to the wheel constituting the lifting means 10.

The ejection means can be integrated in a casing 19.

The ejection means are, according to the invention, actuated by means electric.

Furthermore, the invention provides a specific energy supply electric of these means.

Indeed, the guide means are constructed so that they are at least partially in an electrically conductive material and so that they are in contact with a source of electrical energy and on the other hand, with actuation means.

In this way, the actuating means are electrically powered by the only bias of the guide means without using cables or other means currently used.

Preferably, the electrical actuation means comprise a wire with shape memory 12 shown in different operating phases at Figures 5a to 5d.

We currently know shape memory son which, under the effect of a current, contract and then resume their initial shape when the current is deleted.

Advantageously, the invention may use a shape memory wire 12 able to drive the lifting means 10 in its movement.

To do this, the shape memory wire 12 is fixed on the one hand to the slide 3 and on the other hand to a pull tab 14 driving the lifting means 10.

Such a configuration appears in Figure 5a.

As illustrated, the drive of the lifting means 10 can be carried out by application of the end 23 of the pull tab 14 on one of the wings 11 of the lifting means 10.

By subjecting the shape memory wire 12 to an electric current, it becomes contracts to reach a position illustrated in Figure 5b.

In its movement, it drives the pull tab 14 and the lifting means 10 which rotates.

In doing so, the lifting means 10 raises the lower part of the object 2.

During this movement, the lower part of object 2 passes beyond the upper edge of the stopper 9.

Object 2 is freed as shown in Figure 5c.

This operation carried out, the shape memory wire 12 is released in removing its supply of electrical energy.

It resumes its initial form possibly helped by a body of elastic return to position in the form of a spring 16 in the embodiment illustrated in Figure 5d.

Preferably, the pull tab 14 is provided with a rod 13 capable of translating into a groove 25.

Guidance on the sliding of the pull tab 14 is thus easily operated.

When the object 2 is delivered, the next object 24 is brought by sliding in contact with stop 9.

As indicated above, one of the features of the invention is to allow the actuation means of the ejection means to be supplied by the through guide means.

A particular embodiment of this is described below in more detail. supply in the case where the guide means are constituted by a slide 3 and the means for actuating the ejection means by a shape memory wire 12 as it appears in Figure 6.

One of the advantages of using a shape memory wire 12 is that it does not requires only a low power supply of electrical energy.

In particular, a DC generator can be used.

In the context of the invention, the slide 3 must be electrically connected to this power source.

To do this, an amount 6 as partially shown in Figure 6 can be connected to the power supply and to the rails 3.

The connection to the slides 3 is preferably carried out by means of a front cross member 4 also appearing in FIG. 6.

It is understood that in this context, the cross 4 is, like the slide 3, made at least partially of an electrically conductive material.

Note in Figure 6 the contact made between the cross 4 and the slide 3 in order to establish electrical continuity.

The slide 3 is in turn connected to the wire 12 with shape memory.

There is thus obtained a wire supply circuit 12 without requiring no particular connector element or cable.

The negative or neutral pole of the DC power source allows to constitute the electrical reference of the system and can be pipe to each slide 3 via another upright 7 and a cross member rear 5.

Of course, in order to avoid any short circuit, an insulator 18 is positioned between the cross-member 5 and the slide 3.

Without departing from the scope of the invention, we could have reversed the roles of electrical conduction of the uprights 6 and 7 and of the crosspieces 4 and 5.

A conductor 17 in the form of a flexible wire for example can be used to establish the electrical continuity between the slide 3 and the wire 12 with shape memory.

The invention presented here also relates to an installation for delivery of objects stored online.

This installation is suitable for implementing one or more delivery as described above.

In particular, the delivery devices are integrated into one or more furniture 1, an example of configuration of which is given in FIGS. 1 and 2.

Generally, the storage of drugs is operated within furniture 1.

In addition, the installation will preferably include other elements allowing in particular the control of the delivery devices according to the requests from operators such as a pharmacist.

In this context, it is necessary to be able to control several delivery devices each corresponding to a type of medication from a single station control marked 27 in Figure 7.

To do this, each delivery device is equipped with a command for controlling the electrical means for actuating the means of ejection.

This plurality of control circuits is marked 31 in FIG. 7.

Furthermore, all of the control circuits 31 are connected to a command 28 receiving its instructions from a computer network 26 composed mainly workstations for operators.

In an example configuration, a main station 27 is placed at the end of computer network 26 in order to carry out a global transmission of all the information from the operators to the control card 28 via a link which can for example be a serial type link.

Essentially, the control card 28 includes a microprocessor and an interface capable of managing the data bus towards the control circuits 31 and any accessories 29.

The accessories 29 can in particular be signaling elements or auxiliary actuators.

The bus enabling data transmission has been identified in FIG. 7. between the control card 28 and each of the control circuits 31.

Furthermore, FIG. 7 shows the case of an order for the means actuation in the form of a wire 12 with shape memory.

Of course, the control output of each of the control circuits 31 could have been connected to any type of electrical actuation means.

Advantageously, the electrical energy supply circuit is used for electrical actuation means for transmitting data from control in the direction of the control circuits 31.

To do this, in addition to the connectors already exposed for supplying electrical energy of the actuating means, the power supply is connected to the command 31.

Of course, this unique power and data transmission circuit will be particularly advantageous to implement in the case of using a wire to shape memory which requires only low powers and in particular low voltages.

As part of this data transmission by the power supply, the source of electrical energy will be a direct current generator common to all delivery devices.

Furthermore, the binary data to be transmitted on the bus 30 in a specific way.

Indeed, we transcribe the 0 or the 1 logic by power interruptions of different length depending on whether it is a 0 or a 1.

For example, for a bit at 0, a short interruption of food.

For a bit at 1, the interrupt will be longer.

Of course, the duration of power interruptions will be chosen short enough not to interfere with the supply of electrical energy to means of ejection.

An example of implementation and operation of a installation constituted according to the present invention.

First, an operator such as a pharmacist makes an entry via a control station 27 in the computer network 26.

In particular, a drug delivery instruction will be carried out.

This instruction is transmitted to the control card 28 allowing the centralized management of the set of devices for delivering objects 2 described previously.

Via the supply circuit, an order can be transmitted and understood by a control circuit 31 specific to the drug delivery instruction longed for.

In particular, each control circuit 31 will have an address specific binary coded and transmitted by bus 30 in the form of interrupts successive food.

Once the instruction has been received at one of the control circuits 31, this acts on the electrical actuation means of the ejection means.

In the case of a shape memory wire 12, the control circuit 31 operates a supply of the wire 12 by closing the electrical circuit.

Therefore, the wire 21 retracts causing with it the pull tab 14 and the means elevator 10.

This performs a rotational movement which, when applied to the face lower object 2, allows to raise it out of the stop 9.

Once a sufficient lifting has been carried out, the sliding of the object 2 can be operated by simple action of weight.

Object 2 is then delivered as appearing in FIG. 5d.

According to one possibility, the object 2 is then received by one or more conveyor belts 21 allowing the transfer of the drug to the operator's workstation.

As soon as delivery has taken place, the supply of resources of electrical actuation is cut, and object 24 following object 2 reaches the stop position against stop 9.

The delivery device considered is then ready for a new surgery.

The same sequence of steps can be performed on the same device dispensing to dispense the same type of medication or on another device integrated into the furniture 1 so as to continue the order and deliver all the drugs desired by the operator.

Preferably, the slide 3 incorporates a printed circuit 20 such that shown in figure 6.

It is on this circuit 20 that the control circuit 31 will be positioned.

The printed circuit 20 is moreover connected both to the positive polarity of the power source and negative polarity.

What is more, the printed circuit 20 also allows the fixing of the wire 12 to shape memory.

A variant of the means for ejecting the object is described below, with reference in Figures 8 and 9.

In this context, the lifting means mentioned above consists of a flexible blade 35, for example a thin steel strip. By application of a force at one of the ends of the blade 35 (the other end being fixed), the latter bends.

We use this flexural deformation to push on the underside of object 2, as shown in figure 9.

Preferably, the mobility of the end 37 of the blade 35 is ensured by an electromagnet 39 whose core 38 is connected to said movable end 37.

The electromagnet 39 is supplied by the conductors 17, 34.

It will be noted that the lifting means described as well as the electrical means actuators that drive them can be used independently of the circuit 31 such that the bus 30 is the supply circuit. A system of conventional electrical control (particularly wired) can thus be used, for actuating a shape memory wire 12 than an electromagnet 35.
